Hi everyone, can you explain where I can use this gpu instancing if he can’t work with lightprobe or prebaked GI? I haven’t any ideas

@Aras help you or someone else?
Can someone from engieners send his skype contact? We develop largesize project and we met biiiiiiiiiig problem with optimization.
here is our project. we 3rd place. I’m art from this project.

You can use Light Probe Proxy Volumes to get light probes and instancing to work together.

This don’t work, light probe proxy volume ruin instancing!

You need to be using a shared light probe proxy volume by using the proxy override to point all objects at a single large volume for it to work, not individual volumes for each object. If that doesn’t work then there’s something else you’re doing that’s breaking instancing, or there’s a bug.

no this don’t work. wtf. If lightprobe simply turn on in scenes they destroy instancing. even if I use proxyvolume override for group objects.

hahah :'D

There’s some time since this original post so i’m just wandering if lightprobes still breaks batch and gpu instancing.

If I remember correctly - it’s working:

Thanks Igor. I noticed that this post says the static batch work with lightprobes which give us a good hint about what’s going on.
Anyone knows if the same apply for GPU Instancing? Better asking… does Unity internally handles lightprobes as a per-instance data or some sort of global shared structure? How Probe Proxy Volumes are different on that?

It’s working all the way up
